In this review, we will be comparing EVO4.1 and BW 606, two Passive Bookshelf speakers from Wharfedale and Bowers Wilkins. Let's have a brief look at the main features
of Wharfedale EVO4.1 and B&W 606 first before getting into our more
detailed comparison.
What size room are the Wharfedale EVO4.1 and B&W 606 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Wharfedale EVO4.1 and B&W 606 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer . On the other hand, the BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
EVO4.1 has a frequency range of 64-22k Hz whereas BW 606 has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the BW 606 can go significantly deeper on the low side and provide stronger bass compared to the EVO4.1's min frequency of 64Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
EVO4.1 and BW 606 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.1 sensitivity is rated at 87 dB and the BW 606's is at 88 dB. This 1 dB difference makes the B&W 606 a more sensitive speaker compared to Wharfedale EVO4.1, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
EVO4.1 can handle a max power of 120 watts RMS from the amp the whereas EVO4.1 has a max power handling value of 100 watts RMS , 20 watts less than the BW 606.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Both EVO4.1 and BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale EVO4.1's Post terminals allows Bi-amping or bi-wiring
B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
EVO4.1 has a bottom firing port whereas BW 606 has a rear firing ports. Wharfedale EVO4.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 606 with its rear-firing port.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Wharfedale EVO4.1's and B&W 606's external dimensions. Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm ( 13.1 x 8.2 x 11.6inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .
Wharfedale EVO4.1 is 10mm shorter and 29mm less deeper than B&W 606 but it is also 20mm wider.
Below you can see the front view size comparison of Wharfedale EVO4.1 and B&W 606 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Wharfedale EVO4.1 is approximately 619.5cm2 / 96.0inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The EVO4.1 requires 1% more surface area than the BW 606 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Wharfedale EVO4.1 weighs 7.80kg / 17.2lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the EVO4.1 13% heavier than the BW 606.
Here is a comparison of how EVO4.1 and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.
